摘要
施工实践表明,集料质量不好、粗集料离析、松铺厚度小于设计厚度、碾压工艺不合理等是造成沥青路面施工中集料破碎的主要原因,故施工时应注意采取相应对策,以减少由于集料破碎引起的沥青路面早期破坏的现象。
It is revealed in the construction practices that the main causes of aggregates fractures in asphalt pavement include poor aggregates quality, segregation of coarse aggregates,loose thickness smaller than the design thickness and improper rolling and compacting workmanship. Corresponding solutions should be taken in the course of construction to alleviate early quality defects in asphalt pavement due to aggregate fractures.
